Test Conditions
Clock timing and switching characteristics are specified in
accordance with operating conditions shown in the table
“Recommended DC Operating Conditions.” For all signals other than
PCI signals, AC specifications are characterized at OVDD = 3V and

All signals other
than PCI
TC = 85°C with the 50pF test load shown in the figure at right.
For PCI signals there are two different test load circuits, one for the
rising edge and one the falling edge as shown in the figures at right.
